Description

Slow landing structure for parachute

Technical Field

The utility model relates to a parachute technical field specifically is a parachute is with structure of slowly landing.

Background

The landing of the airborne troops or goods through parachutes has a certain impact force, the weight of the airborne troops is delayed from about zero point two-five seconds to zero point three-second landing through professional training and limb actions when landing, the landing is equivalent to jumping down from a place with a height of two meters, if the limb actions are better to reach zero point 4 seconds landing, the impact force generated by the body and the ground is reduced by about 4 times compared with the former, the probability of injury is greatly reduced, and the longer the interaction time between the impact force and the collided object is, the smaller the impact force is. For example, when someone jumps from a place with several floors of height, the rescue personnel can place an air cushion below the person, so that the person who jumps from building can get about 1 second of chance to get a cushion, and the impact force with the ground can be reduced by hundreds of times.

At present, the manned combat tank at a large station is still a world problem, mainly the impact force to the ground is difficult to overcome, and vehicle-mounted personnel are easy to be injured. The 10-ton unmanned combat tank airborne test is carried out in America and China, a parachute is half a football field large, an air cushion with the height of about 1 m is fixed below the combat tank, the air cushion automatically deflates after the combat tank falls to the ground to obtain the buffer time of about 1 second, the defects are that the parachute of a fighter can float far and then is concentrated on the combat tank for a long time, and the practical value is difficult to achieve. If the war chariot can obtain the buffer time of 2 seconds or more, the manned war chariot or the gun chariot can directly land and immediately put into the battle.

Based on this, the utility model designs a parachute is with slowly structure of landing to solve current parachute and be difficult to overcome the impact to ground, on-vehicle personnel also easily injured's problem.

Detailed Description

The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Referring to the drawings, the utility model provides a technical scheme: the utility model provides a parachute is with structure of slowly touchhing down, includes the elastic cord, and the elastic cord includes bearing rope 2 and elastic material 1, and bearing rope 2 and elastic material 1 are fixed as an organic whole, and the bending of bearing rope is wavy or heliciform, and bearing rope 2 can be straightened completely when aerial, avoids producing the frequency jump at the parachute-jumping initial stage.

The auxiliary ropes are evenly arranged on the elastic rope along the length direction, mechanical lock catches which are loosened at regular time are arranged between every two auxiliary ropes, one auxiliary rope with the same length is arranged on the elastic rope every several meters, if the length of the elastic rope is 50 meters, one lock catch with the auxiliary rope is arranged every 5 meters, the mechanical lock catches are automatically started after the auxiliary ropes are stressed, one auxiliary rope is opened every 5 seconds, and the elastic rope is completely straightened in the air after 45 seconds, so that the generation of frequency jump can be avoided.

The principle of the elastic rope structure in the embodiment is based on the fact that after spiders are connected with a net, when moths hit the spider net, the spider net rebounds for a few times and restores the original dress, that is, because the spider net has a special elastic structure, as shown in the attached drawing 1, the limited tensile rope of the slow landing parachute is designed by means of the structure and the principle of the spider net, and the rope has elasticity and reliable bearing performance, as shown in the attached drawings 2 and 3, wherein the elastic material and the bearing rope must be firmly mixed into a whole.

The common parachute is in a loose state immediately after the heavy object falls to the ground, and the slow landing parachute is still in a tight state within a few seconds designed by people after the heavy object falls to the ground, namely, the parachute has the possibility of dragging the heavy object with certain upward force to realize slow landing.

The slow landing parachute is realized by using a special, stable, reliable and elastic parachute rope to enable the personnel or goods to be landed to have the buffering time of 1 second or longer and utilizing the parachute rope capable of being stretched in a limited mode, and the safety is greatly improved.

The rope of the parachute of the airborne soldier is 20 meters long, only 15 meters under the condition of no load, the rope is stretched to 20 meters when jumping out of the airplane in the air, when the airborne soldier lands, the whole body weight is not grounded, the descending speed of the airborne soldier is about 5 meters per second, when the rope of the parachute of 20 meters retracts to 15 meters, the airborne soldier actually obtains the buffer time of 1 second, the safety is greatly improved, in a wartime state, people can become the airborne soldier after the simple training with enough size, after the special training, the parachute can be made smaller, the elasticity is larger, the parachute descends at the speed of 10 meters per second or 20 meters per second, the airborne soldier can descend from the sky within 1-2 minutes, and the parachute is more favorable for accurate landing due to the reduction of the parachute. The same principle is applied to an aerial-delivery large-tonnage manned combat vehicle, and the like, and if a parachute rope of the combat vehicle with the weight of 10 tons is 100 meters long and is only 70 meters under the no-load condition, and if the parachute rope is stretched to 100 meters under the load in the air, the combat vehicle can obtain the buffer time of 6 seconds with the ground so as to realize the slow landing by assuming that the combat vehicle descends at the speed of 5 meters per second. The light tank with larger weight and even the manned aircraft can return to the earth slowly by using the principle.

In the beach landing operation, the air-drop manned combat vehicles and cannon vehicles are realized through the slow landing structure, a plurality of combat vehicle cannon vehicles can be gathered at a preset beach within tens of minutes, hundreds of airborne troops are enabled to arrive at a specified position in a high-speed airborne mode, and the large-scale naval landing operation is based, so that great advantages are brought.
